I have an idea for a device for the construction industry. Assuming it is actually an original idea I would like to pursue it. I have assorted friends and relatives who could makeup the brain trust necessary to get a prototype going. I've heard a lot of stories about bringing a new invention to market. One is that the larger companies will just defy the patent and outspend you in court until you give up. I friend of my Dad's who claims to have invented a boat anchor that would release when you wanted it to said that's what happened to him. Another is that the Chinese will copy it with virtually no legal recourse. And other times it works out. Wondering if anyone has been on either side of it and what happened.
